This paper model is an A-17 Broadsword Heavy Bomber, a fictional spacecraft found in the Wing Commander, which is a media franchise consisting of space combat simulation video games from Origin Systems, Inc., an animated television series, a feature film, a collectible card game, a series of novels, and action figures. The papercraft was created by Pericles Lopes Gomide.
In the fictional Wing Commander universe, The A-17 Broadsword Bomber was a bomber that featured in Origin Systems' Wing Commander II: Vengeance of the Kilrathi. The Broadsword was manufactured by Douglas Aerospace and was put into service for the Terran Confederation in the year 2635.
In Joan's Fighting Spacecraft (2664.128 update), the Broadsword is the heaviest "fighter" in service with the Confederation military and is classified as a "Heavy Bomber." Origin had designed the bomber, which masses in the area of 100 tons, has very durable armor, powerful shields, and three defensive turrets. These bombers have eight missile hard points with four stressed for anti-capital ship torpedoes. Unlike most smaller craft, the Broadsword bomber mounts a jump drive. In Wing Commander II, Christopher Blair uses this bomber several times, including long-distance assignments requiring jumps to other starsystems.
In the game, the primary complaint by players regarding the Broadsword is the bombers overall relatively slow speed which causes the pilot to have to spend more time on the battlefield and is prone to attacks by the enemy. Origin had designed the bomber to have this weakness and had added three dual neutron gun turrets on the sides and rear of the bomber and three forward firing mass driver cannons mounted in the bomber's nose. The turrets equipped on the bomber can also be used as a tractor beam to haul in ejected pilots or other items such as small satellites and debris. [Source: wikia]
